This page is a consolidated index for previewing the photos mentioned on the Calibrated Full Disk Images page.
Details
This consolidated index, based on the URL and LTVT calibration data files on the parent page identifies
Photographer : name of photographer posting the image, and a link to a web page on which the image is displayed or mentioned.
Date/Time : estimated universal time of the photo. These should be viewed with caution, for a variety of reasons. Nearly all the images are mosaics -- not instantaneous pictures, so they include photos taken over a range of time. In some cases, not in even an approximate time is indicated, so the time had to be guessed from the appearance of the shadows. In others, even though a time was given, it may be in error.
Size (pixels) : full dimensions of the frame, including any dark space or labeling around the lunar image (must match for LTVT calibration data to work with downloaded images).
Diameter : the theoretical size of the full lunar disk (in pixels), based on the observed spacing between the calibration points of known longitude and latitude (assumed to be on the surface of a sphere).
note: what is claimed to be the largest lunar mosaic ever assembled has diameter of 9550 pixels. It is not included in the present list due to the difficulty of providing a URL at which a copy of a definite size can be found. Despite its large size, in many areas its resolution does not exceed that of some of the larger images for which links are provided here.
Rotation : the amount (in degrees) by which the Moon's observed polar axis is rotated clockwise relative to a vertical line. This is based on the direction between the calibration points and, together with the diameter, can be used for resizing the images to a uniform size and orientation independent of LTVT.
Sub-Observer Lon/Lat : the lunar longitude and latitude of the point at the center of the observed lunar disk. These coordinates are commonly referred to as the librations in longitude and latitude.
Sub-Solar Point : the lunar longitude and latitude of the point at the Moon's surface on a line connecting the centers of the Moon and Sun. The position of this point completely determines the lighting of the surface features. It is more often referred to in terms of colongitude (90° minus the longitude -- see below) and latitude.
Image Link : displays the image being referred to. Some images cannot be directly linked to, in which case the name of the file appearing at the end of the link should be consulted. This may be true, for example, of some of the images by Maurice Collins, which may require membership in a particular Yahoo! Group to fully access the directory in which the images are stored. In cases of this sort, click the Photographer link to find the site containing the file mentioned. The file can then probably be downloaded by hand. (note: websites and storage locations on the internet can be very ephemeral. All the links provided here worked at the time the time they were posted, but there is no guarantee they will continue to work in the future.)
Please note that the photographers who have implicitly made their images available for personal viewing and downloading by placing them at the URL's listed below retain all rights to their work. If one wishes to make any use of them other than personal viewing, the photographer should be contacted and suitable permission obtained.
Organization
The images listed on the parent page have been arranged in order of decreasing longitude of the sub-solar point, starting at +180° (a very thin waxing crescent) and proceeding to -180° (a very thin waning crescent). Full Moon images (with a sub-solar longitude near 0° fall somewhere near the middle). Clicking on the images in sequence will follow the progression of the terminator relative to the surface features.
To locate an image based on colongitude proceed as follows: subtract the colongitude (in degrees) from 90, then add or subtract 360, as necessary to put the result in the range -180 to +180. For example, to find an image with a colongitude near 330°, calculate 90 - 330 = -240. This is outside the range -180 to +180, so add 360 to obtain -240 + 360 = +120°. That is the corresponding longitude of the sub-solar point.
Note that the links display the images as posted by the photographers. They vary not only in scale, but also in orientation; and some are mirror-reversed. The images can be displayed much more powerfully and uniformly using LTVT, which requires downloading copies to the user's local storage device. This can be done automatically using the Image Grabber with the files on the parent page. The information used to create the Index is available below in spreadsheet form.
Index
Because of restrictions on the lengths of tables that can be displayed in the Wiki format, the following table has been divided into three parts, with the approximate corresponding lunar phases indicated in the headings. This correspondence is only approximate because (due to the Moon's librations), a Full Moon can be observed from Earth when the Sun's longitude is substantially more or less than 0°.
For those who may wish to sort the data in other ways, the data used to generate the table (including additional calibration data fields) is available as a comma-delimited spreadsheet file. Note that the web page links are in "WikiText" format:
